TO ALL WHOM I'l MAY GONCERN:

Be it known that I, D. P. NIOKERSON, ofl Cleveland, in the county ofCuyahoga, and State of Ohio, have i invented' certain new. and usefulimprovements in Railroad Car-lVheels; and I do hereby declare that thefollowing is a full and complete description of the same, referencebeing-had to the accompanying drawings7 making a part of thisspecification, in which- Figure I is a side view ofV the wheel.

Figure 2 is a view of the opposite side of fig. 1.

Figure 3 is a transverse section of iigs. l and 2, in thc direction ofthe line .1r a.

Figure 4 is a View of the wheel with the internal arrangement detached.

Figure 10 is a view of the wheel with the internal arrangement in place.

TheA other figureslare detached sections, to which reference will be hadin the' description.

Like letters of reference refer to like parts in the diierent views.

This wheel consists of the shell A, iig. 4, provided with a deep rim, B,which forms the tread of the wheel, and a ilange, C, by which it is kepton the rail. D is an annular shoulder, and E a section of asegment-clutch, the purpose of which will hereafter' be shown.Immediately within the rim B is placed a rubber F, Figure 5, thethickness of which being equal to the depth of the rim and shoulder E.This ring is supported from the y centre by the annular metallicshoulder Gr, Figure 6,. encompassed by the ring, as shown in fig. 10.Within the shoulder G is tted another rubber ring, H, Figure S, which issupported from the centre by the shoulder D, by which it is embraced, asshown in fig. 10. This figure shows the relative position of the rim andrings and shoulders to each other when arranged in their order forpractical use. The shoulder D is constructed with a central disk, I, asshown in iig. 3, in which it will be seen that the rim forming theshoulder projects from each Side 0f the Gel'tll disk, and that 621011Side alike is provided with a ring, all of which are; supported by ashaft, J, which forms the axle of the wheel, and 'is bracedv and securedby the hub K. On one arm of the axle is keyed or otherwise secured thecorresponding or relative part L .of the clutch E, and which two partsare made to engage when the wheel `is put together, as shown in tlg. 3,in which is shown a transverse view of the relative position of theseveral parts of the wheel. The side plate M, Figure 9, which is seen inposition in iig. 2, is provided with a shoulder, M', corresponding withthe annular shoulder, D, and which holds the same relation to the wheel.This plate is secured in place by the lugs N or any other suitablemeans. These lugs are made toslide under a slotted rib, O,`soconstructed with an inclination downward as to draw the plate down uponthe shoulders and rings, thereby holding them securely and snugly inplace, but not so tight as to prevent any expansion or contraction ofthe springs. These lugs, when properly secured under the ribs, areprevented from working out by a pin or screw being inserted through theminto the rim of the wheel. By the use of this peculiar wheel it will beevident that `.the weight of the ear is supported by theconcentricrubber springs and shoulders from which it is transmitted to the rim ofthe wheel instead of being applied to the wheel directly. As the weightbears down upon the axle it draws down upon the ring H by means of theprojecting rims of the disk, to which disk the axle is connected, asabove described. This downward draught is resisted by the outer ring Fas the weight is being borne down upon it. Thus the weight issuspended'upon the inner ring and supported froim below by the outer. IIn this `way the carriage is rolled along on a continuously revolv ingspring applied to the inner side ofthe wheel as it is made to run bybeing coupled to the-'disk and the internal arrangement of the clutchesabove described.

By the use of a wheel constructedin this way the ordina/ry springs aredispensed with, the Wheels run with less friction against the sides ofthe rails, and more especially when running on a curve, as they morereadily adjust themselves to the direction of the rail. It also lessensthe downward beating ofV the tread of the -wheels upon the. faces of therails on passing over the ends or when running over the frogs on beingswitched oli` on the side tracks or turn-outs. i

What I claim as my improvement, and desire tosecure by Letters Patent,is-

l. The shell A, elastic ringF, and disk I, provided with the shoulder orilange O, in combination with the elastic rings H. l

2. The clutches L E and disk, in combination with the elastic rings andshell A, substantially as and for the purpose set forth. Y

3. The annular shouldersD M, rings H, plate M, and shell A, arrangedsubstantially as and for the purpose set forth.
